My elderly aspire one D150 is, alas, no longer working (screen dead, not posting either by the sound of it). I've swapped out the ram, checked the battery and charger.

It powers on, no screen activity. The fan is definitely firing up, but it's clearly stopping after 2 seconds, the device does remain on. Key presses yield no additional response.

I did try using an external monitor via the dvi port, but no dice (checking if the monitor is dead).

Any thoughts on fixes, or do I have a new paperweight?
